RELEASING GRAPPLING HOOK OR ANCHOR Original Filed July 27, 1944ATTORNEYS Patented July 15, 1947 UNITED STATES PATENT OFFICE Substitutedfor application Serial No. 546,836, July 27, 1944. This application May7, 1947,

3 Claims.

This is a substitute for prior application Serial No. 546,836, filedJuly 2'7, 1944.

The invention relates to a grappling hook or anchor, and more especiallyto a positive release grappling hook or anchor.

The primary object of the invention is the provision of a device of thischaracter, wherein it can be readily and easily released from engagementwith rock, coral, or other entanglement, and thereby avoiding excessivestrain or damage to the hook or anchor and the haul line.

Another object of the invention is the provision of a device of thischaracter, wherein the hook or anchor proper is slidably supported forfloating action, so that a pull on the fram carrying the same will causeit to engage firmly for anchorage purposes, then on a reverse pull, thedevice will be released with dispatch, and without excessive strain orany damage thereto.

A further object of the invention is the provision of a device of thischaracter, wherein the same will prevent premature release thereofwithattending hazards to ships, boats or other like crafts, and at the sametime eliminating the loss of the anchor line therefor, the device beingof novel construction, and is unique in the working thereof.

A still further object of the invention is the provision of a device ofthis character, which is simple in construction, thoroughly reliable andefficient in operation, strong, durable, conveniently operated, anchoredand released with dispatch, and inexpensive to manufacture and install.

With these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawing, which shows the preferred embodiment of the invention, andpointed out in the claims hereunto appended.

In the accompanying drawing:

Figure l is a perspective view of the device constructed in accordancewith the invention, and shown in anchoring position.

Figure 2 is a similar view, partly in section, showing the device inposition for release.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail A designates generally the device inits entirety constructed in accordance with the invention, while Bdenotes a portion of its hauling line.

The device A comprises a substantially triangular shaped frame In havingthe forwardly convergent elongated arms II and I2, respectively,

the latter arm l2 being formed with an offset union [3 with the arm ll,slightly removed from the forward end M of the same, while this arm I2is provided with a rear elbow l5, disposed at an acute angle to the armII, with an eye linkage l6 therebetween.

Slidably fitted on the arm I l is the runner hub ll of a grappling hookor anchor, having a plurality of hooking tines or members [8, which areradially set to the hub and have their free pointed ends I9 directedforwardly of the latter. The arm H spaced from the linkage I6 isprovided with a stop 20 for the hub to limit the movement thereofrearwardly on the said arm I l.

Loosely embracing the arm I2 is a coupling ring 2|, to which is fastenedthe line B, and this ring travels between abutment points 22 and 23,respectively, on the arm l2 in the working of the device A for theanchoring thereof and its release, accordingly to the direction of pullupon the said line B. This operation can be best seen in both Figures 1and 2, as for example, when the line B is pulled forwardly the ringreaches the point 22, so that the device can be conveniently anchored,then when the said line B is pulled rearwardly the ring 2| reaches thepoint 23, so that the device is released from anchorage.

From the foregoing it is thought that the construction and manner ofoperation of the device will be clearly understood, and therefore, amore extended explanation has been omitted, for the sake of brevity.

What is claimed is:

1. A device of the kind described, comprising a carrier having forwardlyconvergent arms fixed to each other at distant points relative to eachother, a runner on one of the arms, hooks carried by said runner andhaving free ends directed forwardly thereof, and a hauling line looselyconnected to the other arm.

2. A device of the kind described, comprising a carrier having forwardlyconvergent arms fixed to each other at distant points relative to eachother, a runner on one of the arms, hooks carried by said runner andhaving free ends directed forwardl thereof, a hauling line and a ringloosely connecting the line with the other arm.

3. A device of the kind described, comprising a carrier having forwardlyconvergent arms fixed to each other at distant points relative to eachother, a runner on one of the arms, hooks carried by said runner andhaving free ends directed forwardly thereof, a hauling line, a ringloosely connecting th line with the other arm, and a stop on the armcarrying the runner and remote from the forward portion thereof.
